Heberden's nodes typically develop in middle age, beginning either with a chronic swelling of the affected joints or the sudden painful onset of redness, numbness, and loss of manual dexterity. This initial inflammation and pain eventually subsides, and the patient is left with a permanent bony outgrowth that often skews the fingertip sideways.
In smaller joints, such as at the fingers, hard bony enlargements, called Heberden's nodes (on the distal interphalangeal joints) or Bouchard's nodes (on the proximal interphalangeal joints), may form, and though they are not necessarily painful, they do limit the movement of the fingers significantly.
Osteoarthritis of the hand causes stiffness of the base of the thumb, alongside enlargement of DIP and PIP joints, leading to the formation of Heberden's nodes and Bouchard's nodes respectively. [6] Such firm and bony swellings at the finger joints are caused by the growth of osteophytes .
Osteophytes on the fingers or toes are known as Heberden's nodes (if on the distal interphalangeal joint) or Bouchard's nodes (if on the proximal interphalangeal joints). Treatments [ edit ]
A Bouchard's node on the proximal interphalangeal joint of the index finger of a 64 year old man. Bouchard's nodes are comparable in presentation to Heberden's nodes , which are similar osteoarthritic growths on the distal interphalangeal joints , [ 1 ] but are significantly less common.
There is a growing consensus that psychosocial factors are another cause of some MSDs. [11] Some theories for this causal relationship found by many researchers include increased muscle tension, increased blood and fluid pressure, reduction of growth functions, pain sensitivity reduction, pupil dilation, body remaining at heightened state of sensitivity.
Some patients experience serious gastrointestinal problems similar to those of Crohn's disease. About 10 percent of people with reactive arthritis, especially those with a prolonged course of the disease, will develop cardiac manifestations, including aortic regurgitation and pericarditis .
Juvenile idiopathic arthritis (JIA), formerly known as juvenile rheumatoid arthritis (JRA), [1] is the most common chronic rheumatic disease of childhood, affecting approximately 3.8 to 400 out of 100,000 children. [3]
